7475 (AMS4202)

7475 is a controlled toughness alloy. When compared to 7075 aluminium in the same tempers, 7475 aluminium plate typically offers a 40% increase in toughness.

---

Although overall properties are similar to 7075, 7475 aluminium plate offers corrosion resistance and fatigue characteristics which are as good if not better than similar high strength aluminium grades used in the aerospace sector. The product is suitable for applications requiring a combination of high mechanical strength, superior fracture toughness and where resistance to fatigue crack propagation is a consideration.

Stock Availability

We stock 7475 aluminium plates in a wide range of sizes and tempers including T7351 and T7651 tempers.

Use in Aerospace

7475 aluminium alloy plate is a popular alloy for producing fracture-critical components in aircraft, especially when this is a significant design consideration. The alloy finds use in fuselages, wing skins, structural aerospace parts and high stressed components.

Processing Options

We process 7475 aluminium plates in-house to tight tolerances using vertical and CNC plate saws. We stock aluminium plates in incremental sizes, which are closer to your finished requirements.
